MARKING CONTRIVANCE FOR ROLLER STAMPING-MACHINES.

Specification of Letters Patent. Patented J 11113 19, 1917.

Application filed May 13, 1913. Serial No. 767,372.

To all whom it may concern:

Be it known that I, CARL LINDsTRtSM, a subject of the King of Sweden, residing at Berlin 0., Germany, Gr. Frankfurterstr. 137, have invented certain new and useful Improvements in Marking Contrivances for Roller Stamping-h/Iachines, of which the following is a specification.

The invention relates to roller-stampingmachines and its object is to provide means whereby stamps can be marked to prevent the same being again used for commercial purposes. The invention is carried out by forming the periphery of the stamp-afiixing roller and the periphery of the moistening roller with marking means, such as corrugations, ribs, ridges or the like, so that on a stamp being passed between the rollers the same will receive marks or impressions.

In order that my invention may be clearly understood I have hereunto appended drawings, wherein j Figure 1 is a perspective view of the marking contrivance' Fig. 2 shows the arrangement of the same on a roller stamping machine and Figs. 3 and 4 are sectional views taken respectively on the lines 33 and 4-4 of Fig. 2 and 1 I which is provided with a roller 45 in enlooking in the direction of'the arrows.

Inthe drawings 1 is the stamp afhxing roller carried by the shaft 2 journaled in the casing 7 and-provided with marks, corrugations or ridges 3, while 4 represents the moistening roller rotatably mounted on suitable supports 4 pivoted at 4 and controlled by springs 4 whereby the roller 4is maintained in surface engagement with the stamp affixing roller 1 adjacent 'to the marks 3 thereof. The said moistening roller 4 is provided with similar marks, corrugations or ridges 5 arranged in engagement with the marks, corrugations or ridges 3 of the roller 1 and further carries any desired number of annular strips 6 for the purpose of moistening the stamp.

The annular strips 6 of the roller 4' may be maintained in a moistened condition in any suitable manner as for instance by engaging a moistening pad 28 suitably supported in the casing 7 and supplied with water in any desired way as for lnstance from a receptacle located outside of the machine and omitted from the drawings for the sake of clearness. The machine further includes a container 14 located inthe casing 7 and in which the strip of stamps 13 in the form of a roll is rotatably supported, saidstrip of stamps passing over a table 15 rlgidly mounted in the casing 7 and beneath a tension spring 16 carried by said table to the rolls 1 and 4. An arm 17 is pivotally mounted at 17 in the casing 7 and is maintained in contact with the periphery of a cam 17 by means ofa spring 17, said cam 17 being carried by a shaft 42 rotatably ournaled in said casing 7. At its lower end the arm 17 carries a spring pressed pawl or finger 17 d which engagesthe strip of stamps 13 and serves to feed it between the table 15 and tension spring 16 toward the rollers 1 and 4 as will appear more fully hereinafter.

A plunger 18 is located over the table 15 and under the influence of an eccentric 18* carried by the shaft 42 is arranged to periodically press said strip of stamps upon the table 15 whereby the stamp strip is clamped against movement and separation of certain stamp or stamps from the said strip takes place aswill be more fully explained further on in the description. An additional roller 8 is located beneath the roller 1 and is mounted on a shaft carried by arms 47 secured to a shaft 46 journaled'in the casing 7 and carrying a lever 45 the free end of with a gear wheel 40 located on the shaft 2,

whereby rotary motion is transmitted to the roller 1, said shaft 42 being actuated through the medium of an operating crank or handle 43. A table 10 is located adjacent to the rollers l and 8 and extends through a slit 9 in the front wall of the casing 7 as shown in Fig. 3.

In operation the handle 43 is continuously rotated in the direction of the arrow in Fig. 3 to rotate the shaft 42 and through the medium of the gears 41 and 40 brings about a rotation of the roller 1 which in turn communicates a similar movement to the rollers 4 and 8 owing to the factthat these two rollers are in surface engagement therewith. At the same time the cam 44 will be operated and will actuate the lever 45 and rock the shaft46 and thus move the roller 8 away;

from the roller 1 against the tension of the spring The rotation of the shaft :42 by means of the handle t3 also brings about an actuation of the cam 17 so that the arm 17 is rocked in one direction on its pivot 17' during which the pawl 17 slides over the strip of stamps 13 in an inoperative movement toward the right in Fig. 4:. As the actuation of the mechanism is continued the :am 17 will be further rotated and will thus permit the spring 17 to draw the arm 1'7 backtoward the left in Fig. and the pawl 17 to engage and feed the stamp strip toward the stamp affixing roller 1 and the rollers between which rollers 1 and ,1 said strip passes. The stamps pass between said rollers 1 and at witlnthe gummed surfaces uppermost and through the coiipera tion of said rollers are marked and firmly pressed into the marks, corrugations or ridges 3 by the marks 5, while at the same time the gunnned surfaces are properly moistened by the moistening strips 6 of the roller Tl. In this manner the stamps become firmly alfiXed upon the corrugations 3 of the roller 1 and are carried along with said roller as rotation thereof continues. In the meantime the envelops are passedthrough the slot 9 and are fed along the table.10 between the rollers 1 and 8 which have been separated by the action of the cam H on the lever 45, shaft 4.6 and arms 4:7. The cam 41 is propertioned so as to maintain the roller 8 out of contact with the rollerl for a sutiicient period to permit the envelops. to becomeproperly positioned between therollers 1 and 8 to receive the stamp, the spring52 serving to return theroller S into engagement with the roller 1 as soon as theaction of the cam let on the roller 15* ceases. The stamps having during this operation been carried along by the roller 1 finally have their moistened, gummed surfaces brought into contact with the envelops andthrough the combined action of the rollers 1. and S arefirinly pressed upon said envelops and thus caused to adhere thereto. Asthe mechanism is operated as described the eccentric 1S will at .the proper time cause the plunger lS to descend and clamp the strip of stamps 13 on the ,table .15 against further movement until again released through a lifting of said plunger 18. As the strip of stamps 18 is thus held a pull will be exerted on thatportion thereof to the left of said plunger 18 in Fig. l by the continued rotation of the rollers .1 and r and will thus separate a ,predetermined number of stamps from the strips for application to the envelop or the like. It will of course, be understood that lthe eccentric is so arranged as to periodically raise and lower the plunger at the proper times to securethe desired results. After the stamps have been properly affixed to the envelop as described the stamped envelop is fed along between said rollers 1 and 8 and finally passes down a suitable chute out ofthe casing 7. The roller 8 firmly presses each successive envelop against the roller 1 and the gummed surfaces of the stamps carried thereby and consequently cause the said stamps to adhere to the envelops and to. be released from the corrugations 3 of the roller 1. In order to keep a correct account of the value of the stamps which have been usedin the machinethe registering device 11 may be provided. This device is actuated during rotation of the shaft l2 by means of suitable mechanism carried by said shaft, said mechanism being capable of being adjusted or set through the medium of the device 12 which as shown comprises a cooperating notched wheel, and spring pressed plunger adapted to be adjusted relatively to each other. According to the adjustment of the meehanismifor ac tuating the device .11, the latter will be tripped one or more times during, eachrotation of the shaft 42 and will thus add. up the amounts ofthe stamps which are used. For instance the device 11 may be adapted for one cent units, so that iffive cent stamps are to be used the mechanism will be set to actuate said device 11 fivetimes during each rotation of the shaft .42 whereby five cents, in one cent units, will be added to; the previous total at each operation of said shaft 42.

Various changes in the arrangement shown and describedmay be made within the scope of the claims without departing from the spirit of my invention.
